Introduction

A textile manufacturing company had experienced repetitive failures at approximately 6 months in air circulation motor-fans used on their fabric furnace. During an onsite inspection, NSK found out a relatively high operating temperature in the furnace. Taking this into account, NSK proposed an alternative Deep Groove Ball Bearing type, designed specifically for the use in applications with higher temperatures. A trial was initiated which demonstrated that the bearing life was extended twice compared to standard products. This resulted in a significant reduction in maintenance costs, no unplanned breakdowns and a subsequent improvement in productivity.

 

Key Facts

  • Special textile manufacturing plant
  • Fabric furnace motor-fan
  • Repetitive failures experienced between planned maintenance shut downs
  • Bearing failing due to high operating temperatures
  • NSK Solution: NSK proposed an alternative Deep Groove Ball Bearing for high temperature applications
  • A trial showed that the bearings lasted more than twice than standard units
  • No unplanned failures in a 12 month period
  • Consequently a cost saving was realised due to reduced maintenance and no lost production
  • Textile Manufacturing Deep Groove Ball Bearing with high temperature seal

Value Proposals

  • The customer explained they were having repetitive bearing failures in their furnace motor-fan
  • An NSK application revie identified the cause was the high temperatures generated in the furnace
  • The customer mentioned they were using standard Deep Groove Ball Bearings in the motor-fans
  • NSK proposed a trial using high temperature Deep Groove Ball Bearings
  • The trial was successful with no bearing problems in over a year
  • This resulted in a significant cost saving due to reduced maintenance and no lost production
